Sal Mineo guest stars as Joey Hopper, the Manson-like head of a Satanist cult known as the Butcher Brigade. Escaping from a prison hospital ward with the help of his "family," Hopper swears vengeance against all the jury members that found him guilty of murder. The SWAT team's efforts to track down Hopper are stymied by obstreperous underground-newspaper publisher Ross Collins (William Windom), who might not be so sympathetic toward Hopper if he knew that his own daughter Judy (Belinda Balaski) aided in the cult leader's bloody escape.
